* add stdio_usb_connected() method
* add PICO_STDIO_USB_CONNECT_WAIT_TIMEOUT_MS to allow waiting for CDC connection during init(*
* add puts_raw and putchar_raw to skip any CR/LF translation
Fixes build when pico_stdlib isn't included in the target libraries:
pico-sdk/src/rp2_common/pico_divider/divider.S:8:10: fatal error: hardware/divider_helper.S: No such file or directory
Also fixes the same error in pico_double, though I'm not sure how/why:
pico-sdk/src/rp2_common/pico_double/double_aeabi.S:9:10: fatal error: hardware/divider_helper.S: No such file or directory
* use PICO_DISABLE_SHARED_IRQ_HANDLERS exclusively as config for no shared handler support (rather than also PICO_MAX_SHARED_IRQ_HANDLERS == 0)
additionally make irq_add_shared_irq_handler() call irq_set_exclusive_handler() so that single usage of an IRQ still works
* Comment typo

* Add missing DREQ_s
* store actual clock frequency in clock_configure (fixes#368)
* use dma DREQ values defined in dreqs/dma.h
* Fix hw_is_claimed, and add xxx_is_claimed APIs
* Add some PIO irq helper methods
* Add DMA channel IRQ status getter and clear methods
* Implement the correct PIO IRQ status/clear methods (good to have methods here as the h/w interrupt registers are super confusing)
* fix pico_multicore dependencies
* add missing wrapper func __aeabi_f2d
* Further DMA/PIO IRQ API cleanup (and review fixes)
* add PICO_INT64_OPS_IN_RAM flag
Most build related items have moved into <tinyusb>/hw/bsp/rp2040/family.cmake which is now the source of truth
force merging as same code save submodule was already reviewed
* - fix interp_claim_lane (in case of interp1 and lane==1 bit was 0b11 instead of 0b1000)
- added missing function interp_unclaim_lane_mask
* - interp_hw_save_t are not I/O registers
* Fix warnings about some unused parameters in pico_stdio_usb
* Use `__unused` for the unused parameter in tud_descriptor_configuration_cb
* Remove redundant inclusions of `pico/platform.h`
This header is included by the other library headers (via `pico.h`)
- The divider state needs to be saved for __aeabi_ddiv, __aeabi_fdiv, __aeabi_dtan and __aeabi_ftan or they won't work in interrupts *(probably not used much youd hope), or on an RTOS context switch
- Refactored code out for the integer and floating point cases
- Improved the floating point 'tests' in passing to check more return values against GCC implementations
- Added floating point usage to the IRQ nesting test case
Adds a new cmsis_core INTERFACE library, which provides the basic CMSIS macros/definitions, and RP2040.h and system_RP2040.h
By default the isr_ methods in the vector table are renamed to their CMSIS versions, but this can be overridden by defining PICO_CMSIS_RENAME_EXCEPTIONS=0
